jhat: Analyze a dump letting `jhat` use up to 8 GB RAM (2-4x dump size recommended).
$ jhat -J-mx8G ${dump_file-bin}
try on your machine

The command you provided is a command-line command. Here is the breakdown of its components:

  1. jhat: This is the command itself, which is used to run the Java Heap Analysis Tool (JHAT). JHAT is a tool that comes with the Java Development Kit (JDK) and is used for analyzing heap dumps.

  2. -J-mx8G: These options are passed to the Java Virtual Machine (JVM) when running JHAT. -J is used to pass options to the JVM. In this case, -mx8G sets the maximum heap size for the JVM to 8 gigabytes (8G).

  3. ${dump_file-bin}: This is a placeholder for the path to the heap dump file you want to analyze using JHAT. The ${dump_file-bin} suggests that it is using a variable or placeholder, and you would need to replace it with the actual path to your heap dump file.

To use this command, you need to replace ${dump_file-bin} with the actual path to your heap dump file, and then run the command in your command-line interface. It will launch JHAT and perform heap analysis on the specified heap dump file, using a maximum heap size of 8 gigabytes.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
